I think he was like that at first, but in the past couple seasons(especially this one) he's set up other team mates for goals. Of course with his raw talent and ability to get by any defender, he's gonna take advantage of that. 41 goals is just ridiculously impressive. He hasn't really showed up in big games though, either for Portugal or Man U so I'm trying to see what he's gonna do today.
But I could see how people don't like him. I hated him at first but now I love to watch him play
